N2 - Recently, novel imaging techniques based on the “memory-effect” speckle-correlations have enabled diffraction-limited imaging through scattering layers and around corners. These techniques, however, are currently limited to imaging only small planar objects contained within the angular and axial range of the memory effect. In addition, they do not provide depth information or depth-sectioning capability. Here, we extend speckle-correlation imaging to include high-resolution depth-sectioning capability in the reflection mode, by combining it with coherence gating via low-coherence holography. We demonstrate depth measurements of reflective targets through a scattering layer, and speckle-correlation imaging using coherence-gated scattered light.
